New to Linux: Best practices for system cloning/imaging for disaster/backup recovery

In the next year we are migrating our system from a Windows system to a Linux system with all RHEL machines (desktops & servers).

I am in the process of learning linux and one of my tasks is to create system clones/images in case of a disaster or installing new machines so we all have one standard for each machine.

I have research some different softwares for example clonezilla seems to be the most popular.

I tested sysrescucd with PartImage but that doesn't support Ext4.

In testing clonezilla it seems to work fine but when I boot up the machine that I just recently but the new clone on...it makes me enter in the encryption password through a command line rather than through the simple gui that RHEL supplies on my desktop that I used to clone.

I am not sure if there are softwares out there that you can pay for that are better than others.

Just want to get some opinions on what the best softwares are out there for me to use.

Clonezilla seems to work fine but its just when I putt the clone image on the new machine the boot up seems different and it shows a lot of command line data when booting up rather than showing the rhel loading image.

Also clonezilla seems to take a long time to get the image and to upload the image (like an hour and half for each) and I don't have much data on the imaged machine.

Hopefully all of this makes sense it was just a bunch of rambled stuff I put together quick.

Thanks.
